摘　　要：目的观察不同区带良性增生结节经直肠超声造影特征,并探讨其与血管生成的相关性。方法对62例患者穿刺活检证实为良性增生的62个低回声结节(移行区结节32例,周围区结节30例)行经直肠前列腺超声造影(CETRUS),并观察MVD的表达情况。结果周围区低回声增生结节与移行区增生结节超声造影表现不同,差异有显著统计学意义(P<0.01)。造影峰值强度(PI)与MVD值显著相关(r=0.51,P=0.01)。结论不同区带良性增生结节血管生成特征显著不同,CETRUS能提供血管生成的临床信息。Objective To investigate the vascularity of zonal location of benign hyperplastic nodules, and to determine the clinical value of contrast-enhanced transrectal ultrasound for assessing vascularization of the prostate gland. Methods Sixtytwo patients with hypo-echoic biopsy-proven BPH nodules in transition zone （TZ） （32 patients） or peripheral zone （PZ） （30 patients） of the prostate underwent contrast-enhanced transrectal gray-scale ultrasonography （CETRUS）. In addition, microvessel density （MVD） was determined in the biopsy specimens. Findings were compared between two groups. Correlation between PI and MVD was also investigated. Results There was significant difference in enhancement pattern between PZ and TZ benign hyperplastic nodules （P〈0.01）. PI was found to be important parameter strongly correlated with degree of vascularity of zonal location of hyperplastic nodules （r=0.51, P=0.01）. Conclusion The hyperplastic nodules located in different zones of the prostate （PZ and TZ） showed significant difference in vascularity. CETRUS could afford information of the vascularization of BPH.
